The Asymptotics of an Amplitude for the 4-simplex

  title={The Asymptotics of an Amplitude for the 4-simplex},
  author={John W. Barrett and Ruth Mary Williams},
An expression for the oscillatory part of an asymptotic formula for the relativistic spin network amplitude for a 4-simplex is given. The amplitude depends on specified areas for each two-dimensional face in the 4-simplex. The asymptotic formula has a contribution from each flat Euclidean metric on the 4-simplex which agrees with the given areas. The oscillatory part of each contribution is determined by the Regge calculus Einstein action for that geometry.
